## Khan Academy Activity

Today we are going to discover and explore more about triangles! I thought it'd be a great idea to do some interactive/discovery work with them. Below are three activities that I would like you to complete.

Activity 1: Learning more about when triangles are congruent to each other! You've already used SSS and SAS, but now you'll discover AAS and ASA! In this activity you'll be given one of many triangle postulates, but don't get fooled because they'll try to give you ones that aren't as well. To do the activity, click and move on the YELLOW dots to make a triangle. If ONLY 1 can be formed, then click yes on the right side. If 2 or more can be formed, click no on the right side.To begin click HERE.

Activity 2: In this activity you'll be given 2 triangles. If they appear to be congruent through SSS, SAS, AAS, or ASA, then click yes. If we can't tell because they are SSA or AAA, then click not enough information. If they aren't congruent, click no. Begin the activity by clicking HERE.

Activity 3: In this activity, you'll be using the idea of congruent parts, 180 degrees in a triangle, and 180 degrees in a line to find missing values. Begin by clicking HERE.

EXTRA ACTIVITY: If you have finished all the above activities, try this one on for size by clicking HERE.
